The axle load of a wheeled vehicle is the total weight bearing on the roadway for all wheels connected to a given axle.Axle load is an important design consideration in the engineering of roadways and railways, as both are designed to tolerate a maximum weight-per-axle (axle load); exceeding the maximum rated axle load will cause damage to the roadway or railway tracks.
The drive axle may be a live axle, but modern rear-wheel drive automobiles generally use a split axle with a differential. In this case, one half-axle or half-shaft connects the differential with the left rear wheel, a second half-shaft does the same with the right rear wheel; thus the two half-axles and the differential constitute the rear ...
Route availability for a vehicle (locomotive or wagon) is generally based upon its axle loading. That is, how much of the laden weight of the vehicle is distributed on each axle. The more weight on each axle, the higher the RA number, and the more restricted the vehicle is. For wagons it is normal to have different RAs when running empty and full.
A preserved GWR 4500 Class steam locomotive, showing power classification "C" on a yellow route restriction disc, on the upper cab side-sheet. On 1 July 1905 the Great Western Railway (GWR) introduced a system for denoting both the haulage capabilities and the weight restrictions which applied to their various classes of locomotive.
Cheater axle See lift axle. Dual wheels A pair of tire and wheel assemblies mounted side-by-side on a single axle hub. In some applications it is replaced by a super single. On pickup trucks it is sometimes called a dually. The assembly has a greater load carrying ability as compared to a single wheel.
When evaluating the series of tests, it was found that there is a connection between the thickness of the pavement, the number of load transfers and the axle load, and that these have a direct effect on the service life and condition of a road. The service life of the road is thereby reduced with approximately the fourth power of the axle load. [1]

The change in material stress deforms the sensor, in which strain gauges are mounted as in a classic load cell. Thus, the weight of the individual wheelset or bogie can be calculated from the specific deformation behaviour of the rail. Advantages: Can be used as a wheel load scale and axle load scale,
